9911 Quantz is an S-type main belt asteroid. It orbits the Sun once every 3.49 years. [cite web|url = http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9911 | title = 9911 Quantz (4129 T-2) | work = JPL Small-Body Database Browser | publisher = NASA/JPL | accessdate = 2008-02-04]

Discovered on September 29, 1973 by Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld on photographic plates that had been taken by Tom Gehrels with the Samuel Oschin telescope at the Palomar Observatory, it was given the provisional designation "4129 T-2". It was later renamed "Quantz" after Johan Joachim Quantz, a seventeenth century German music teacher and composer. [MPC 34356 "Minor Planet Center"]
